• Paradigm level: e.g. long term evolution in societal value
systems and prioritization structures
• scenario choices; delineation; (model type choice)
• Conceptual level: understanding of the causal structure
• Model (type) choice; model structure; data sources/needs
• Model level: sufficiently adequate representation of the causal
structure and orders

Monte Carlo analysis, multiple model simulation, NUSAP, quality assurance, scenario analysis, sensitivity analysis, stakeholder involvement
and uncertainty matrix. The applicability of these methods has been mapped according to purpose of application, stage of the modelling process
and source and type of uncertainty addressed. It is concluded that uncertainty assessment is not just
